Battery charging issue after factory reset

I don't think a factory resetting will help your current battery charging issue.

It is recommended to unplug the USB cable to reconnect or replace this USB cable at first since you are sure that the battery is not damaged at all. Good luck to you.

If this does not work yet, go to the nearest Lenovo Customer Service Center for a professional battery performance check.

After a factory reset, you can try a few things to fix the fast charging issue on your Moto Edge 20 lite.

Ensure you use the original charger and cable that came with your phone. If you are using a third-party charger or cable, it may not be compatible with fast charging.
Try a different outlet. If you are charging your phone from a power outlet, try another outlet to see if that makes a difference.

Motorola releases software updates for its phones regularly. These updates often include bug fixes and performance improvements. Go to Settings > System > System updates to update your phone's software.

Reset the charging preferences. Go to Settings > Battery > Battery usage > Three dots in the top right > Battery preferences > Charging. Make sure that "Fast charging" is turned on.

Factory reset your phone. As a last resort, you can try factory resetting your phone. This will erase all of your data, so back up your phone before you do this. To factory reset your phone, go to Settings > System > Advanced > Reset options > Erase all data (factory reset).

If you have tried all these steps and still have problems with fast charging, you may need to contact Motorola for further assistance.

I can tell you what worked for me, what i did was this used to only the authorized chargers.
